Abstract

Disclosed are compositions, systems and methods for treating keratinous fibers such as hair. The compositions and systems comprise an oxazoline functionalized polymer and a polyamine compound. The compositions and methods are employed to improve the quality of the keratinous fibers.

First claim

The invention claimed is:

1. A composition for treatment of keratinous fibers comprising:
at least one oxazoline functionalized polymer; and
at least one polyamine compound;
wherein the at least one oxazoline functionalized polymer is formed by polymerizing monomers having an oxazoline-type functional group of the following formula (I):

wherein in formula (I),
R 1 , R 2 , R 3 , and R 4 represent, independently of each other, hydrogen, a halogen, an alkyl, an aryl, alkoxyalkyl, or alkoxyaryl; and
R 5 is an organic group bearing a radical polymerizable vinyl bond.

2. The composition according to claim 1 , wherein the at least one oxazoline functionalized polymer is chosen from a waterborne crosslinker polymer, a granule type, or a mixture thereof.

3. The composition according to claim 2 , wherein the at least one oxazoline functionalized polymer is a waterborne crosslinker polymer chosen from acrylic-based oxazoline functionalized polymers, styrene/acrylic-based oxazoline functionalized polymers, or a mixture thereof.

4. The composition according to claim 1 , wherein the polyamine compound is chosen from non-alkoxylated polyamines, alkoxylated polyamines, or a mixture thereof.

5. The composition according to claim 4 , wherein the polyamine compound is a non-alkoxylated polyamine chosen from polyvinylamines, aminated polysaccharides, amine substituted polyalkylene glycols, amine substituted polyacrylate crosspolymers, amine substituted polyacrylates, amine substituted polymethacrylates, amine substituted polyesters, polyamine acids, polyalkylamines, diethylene triamine, triethylenetetramine, spermidine, spermine, aminosilicones having at least two amino groups, or a mixture thereof.

6. The composition according to claim 5 , wherein the polyamine compound is chosen from polyvinylamines.

7. The composition according to claim 5 , wherein the polyamine compound is chosen from alkoxylated polyamines.

8. The composition according to claim 1 , wherein the at least one oxazoline functionalized polymer is present in a concentration, by weight, of from about 0.1% to about 20%, based on the total weight of the composition.

9. The composition according to claim 1 , wherein the at least one polyamine compound is present in a concentration, by weight, of from about 0.001% to about 20%, based on the total weight of the composition.

10. The composition according to claim 1 , wherein the mole ratio of the oxazoline group(s) of the at least one oxazoline functionalized polymer to the amino group(s) of the at least one polyamine compound is greater than 1.

11. The composition according to claim 1 , wherein the mole ratio of the oxazoline group(s) of the at least one oxazoline functionalized polymer to the amino group(s) of the at least one polyamine compound is less than 1.

12. The composition according to claim 1 , wherein the mole ratio of the oxazoline group(s) of the at least one oxazoline functionalized polymer to the amino group(s) of the at least one polyamine compound is from between about 80:1 to about 1:80.

13. The composition according to claim 1 , further comprising a solvent selected from water, organic solvents, or a mixture thereof.

14. The composition according to claim 1 , wherein the keratinous fibers include hair, and wherein the composition is formed in-situ on the hair from a step-wise application on the hair of a first composition comprising the at least one oxazoline functionalized polymer and a solvent, and a second composition comprising the at least one polyamine compound and a solvent, wherein the solvents in the first and second compositions are independently chosen from water, organic solvents, or mixtures thereof.

15. The composition according to claim 1 , wherein the composition includes amounts of each of the at least one oxazoline functionalized polymer and the at least one polyamine compound sufficient to impart to the keratinous fibers after application thereto, one or more of hydrophobicity, manageability, and frizz control.

16. The composition according to claim 15 , wherein the hydrophobicity imparted to the keratinous fibers includes a contact angle of greater than 85°.

17. The composition according to claim 15 , wherein the hydrophobicity imparted to the keratinous fibers confers high humidity curl retention after a period of exposure to humidity ranging from about 40% to 90%.

18. The composition according to claim 15 , wherein the hydrophobicity imparted to the keratinous fibers is durable even after one or more wash cycles.

19. A method of treating keratinous fibers, comprising applying onto keratinous fibers, the treatment composition of claim 1 .

20. The method according to claim 19 , further comprising a step of heating the fibers during, before, and/or after the treatment composition is applied onto the fibers.

21. The method according to claim 19 , wherein the method imparts to the keratinous fibers after application thereto, one or more of hydrophobicity, manageability, and frizz control.

22. The method according to claim 21 , wherein the method imparts a hydrophobicity to the keratinous fibers resulting in a contact angle of greater than 85°.

23. A method of imparting hydrophobicity and/or manageability to keratinous fibers chosen from hair and/or protecting keratinous fibers chosen from hair from extrinsic damage caused by heating, UV radiation, chemical treatment or mechanical stress, or of repairing a keratinous fiber chosen from hair following extrinsic damage caused by heating, UV radiation, chemical treatment, or mechanical stress comprising: applying to the keratinous fibers a composition according to claim 1 ; and optionally heating the keratinous fibers; wherein when heating is employed, the composition is applied prior to the heating, during the heating, or after the heating.

24. The method according to claim 23 , wherein the method is a process selected from:
a one step process, wherein the composition comprising the at least one oxazoline functionalized polymer and the at least one polyamine compound is provided as a single composition, and is prepared by combining the at least one oxazoline functionalized polymer, the at least one polyamine compound, and at least a solvent, whereby the single composition is applied onto the keratinous fibers;
a one step process, wherein the composition is provided in separate treatment compositions, each separately comprising the at least one oxazoline functionalized polymer and the at least one polyamine compound, the treatment compositions prepared by combining the at least one oxazoline functionalized polymer with at least water to form a first phase, and separately combining the at least one polyamine compound with at least one a solvent selected from water, organic solvents, or a mixture thereof to form a second phase, whereby at the time of use, the phases are combined and agitated to form a mixture that is applied onto the keratinous fibers; and
